Bone and Joint Imaging. Here images of a patient with breast cancer. Check for errors and try again. The diagnosis was fibrous dysplasia. Sarcoidosis is a multi-system disease with a range of . Bone flare phenomenon was well described on bone scans; a study 25 revealed the appearance of new or worsening bone sclerosis at 3-month CT assessment in three of 67 castration-resistant prostate cancer (CRPC) patients undergoing systemic treatment. The differential diagnosis for bone tumors is dependent on the age of the patient, with a very different set of differentials for the pediatric patient.

Here a partially calcified mass against the proximal humerus with involvement of the cortical bone on an axial CT image. Fisher C, DiPaola C, Ryken T et al. Journal of Bone Oncology. Sclerotic osteoblastic metastases must be included in the differential diagnosis of any sclerotic bone lesion in a patient > 40 years. However, a specific density range has not been specified for those terms 1. The diagnosis is usually established by a combination of imaging and the known presence of a primary tumor that is associated with sclerotic bone metastases. Osteoblastic metastases (2) However, a specific density range has not been specified for those terms 1. The major part of the lesion consists of reactive sclerosis. Rapid growth of the mineralized mass is not uncommon. Purpose: To determine if sclerotic bone lesions evident at body computed tomography (CT) are of value as a diagnostic criterion of tuberous sclerosis complex (TSC) and in the differentiation of TSC with lymphangioleiomyomatosis (LAM) from sporadic LAM. Ask the patient or the clinician about this. Solitary sclerotic bone lesion. In some cases however the osteolytic nidus can be visible on the radiograph (figure). Based on the morphology and the age of the patients, these lesions are benign. Metastases and multiple myelomaIn patients > 40 years metastases and multiple myeloma are the most common bone tumors.Metastases under the age of 40 are extremely rare, unless a patient is known to have a primary malignancy.Metastases could be included in the differential diagnosis if a younger patient is known to have a malignancy, such as neuroblastoma, rhabdomyosarcoma or retinoblastoma. Ossifications or calcifications can be present in variable amounts. A mean CT attenuation threshold of 885 HU and a maximum attenuation threshold of 1060 HU has been found supportive in the differentiation of untreated osteoblastic and bone island in one study 7, but the exclusive use of attenuation values for the assessment of sclerotic bone lesions has been discouraged 8. There are two kinds of mineralization: Chondroid matrix Sclerotic bone lesions caused by non-infectious and non-neoplastic diseases: a review of the imaging and clinicopathologic findings Sclerotic bone lesions caused by non-infectious and non-neoplastic diseases: a review of the imaging and clinicopathologic findings Authors Once we have decided whether a bone lesion is sclerotic or osteolytic and whether it has a well-defined or ill-defined margins, the next question should be: how old is the patient? In this paper, we review the recent years of literature on deep learning-based multiple-lesion recognition. and PD-L1 PET/CT (PD-L1 positivity is defined as having at least one lesion with radiotracer uptake over the . Solitary lucent lesions in bone with a distinct margin are generally called "geographic" lesions, whether or not they have a sclerotic rim. Oncol Rev. 20 yo M w/ 5 cm lytic bone lesion in proximal tibia metaphysis, sharply demarcated w/ sclerotic rim. 2016;207(2):362-8. A high grade chondrosarcoma must be considered in the differential diagnosis. The juxtacortical mass has a high SI and lobulated contours. A chondrosarcoma was diagnosed at biopsy. Usually stress fractures are easy to recognize. In this article we will discuss the differential diagnosis of sclerotic bone tumors and tumor-like lesions in more detail. Isaac A, Dalili D, Dalili D, Weber M. State-Of-The-Art Imaging for Diagnosis of Metastatic Bone Disease. Arthritis Rheum., 42 (2012), pp. Despite their remarkable clinical success, the low degradation rate of these materials hampers a broader clinical use. Differential Diagnosis in Orthopaedic Oncology. Urgency: Routine. Most commonly encountered bone tumor in the small bones of the hand and foot. If the patient had fever and a proper clinical setting, osteomyelitis would be in the differential diagnosis. Bone cements such as polymethyl methacrylate and calcium phosphates have been widely used for the reconstruction of bone. Radiographs typically show a geographic lytic or ground glass lesion with a well-defined, often extensively sclerotic margin, indicating its indolent nature. It can differentiate predominantly osteoblastic from osteolytic bone metastases 9 as well as easily demonstrate and assess complications such as pathological fractures or spinal cord compression 2,3. (2007) ISBN: 9780781779302 -. CT imaging example of the location pattern of sclerotic bone lesions in the skull, spine, and pelvis of TSC patients and control subjects. Central location most common with some expansion and cortical thinning. 6. In aggressive periostitis the periosteum does not have time to consolidate. If the lesion grows more rapidly still, there may not be time for the bone to retreat in an orderly manner, and the margin may become ill-defined. This feature differentiates it from a juxtacortical tumor. Bone reacts to its environment in two ways either by removing some of itself or by creating more of itself. Mark Blumenkehl, MD is a specialist in Gastroenterology whose practice locations include: Detroit, Sterling Hgts Physical examination and past medical history were normal and noncontributory respectively. A 30-year-old woman underwent a CT of the pelvis for endometriosis and an incidental lesion was found in the sacrum. The cortical bone and bone marrow compartment are not involved. Plain films typically reveal lesions with moth-eaten or permeative pattern of the transition zone with irregular cortical destruction and an interrupted periosteal reaction with soft tissue extension. Finally other clues need to be considered, such as a lesion's localization within the skeleton and within the bone, any periosteal reaction, cortical destruction, matrix calcifications, etc. ( A1,A2) Transversal CT of the skull of a TSC patient and . Lets apply the good old universal differential diagnosis to sclerotic bone lesions. Calcifications or mineralization within a bone lesion may be an important clue in the differential diagnosis. 3. The differential diagnosis mostly depends on the age of the patient and the findings on the conventional radiographs. Yes, it is possible to have a clear lumbar puncture and still have Multiple Sclerosis (MS). The sclerotic lesion in the humeral head could very well be a benign enchondroma based on the imaging findings. Complete destruction may be seen in high-grade malignant lesions, but also in locally aggressive benign lesions like EG and osteomyelitis. The homogeneous pattern is relatively uncommon compared to the heterogeneous pattern. AJR 1995;164:573-580, Online teaching by the Musculoskeletal Radiology academic section of the University of Washington, by Theodore Miller March 2008 Radiology, 246, 662-674, by Laura M. Fayad, Satomi Kawamoto, Ihab R. Kamel, David A. Bluemke, John Eng, Frank J. Frassica and Elliot K. Fishman. In the epiphysis we use the term avascular necrosis and not bone infarction. World J Radiol. A juxtacortical chondrosarcoma has be considered in the differential diagnosis when a mineralized lesion adjacent to the cortical bone is seen. Here a lesion located in the epi- and metaphysis of the proximal humerus. The radiological report should include a description of the following 2: location and size including the whole extent of disease load, pain attributable to the lesion (if known), Treatment of bone metastases, in general, is usually planned by a multidisciplinary team 10. Donald Resnick, Mark J. Kransdorf. If the osteonecrosis is located in the epiphysis, the term avascular osteonecrosis is used. Ossification in parosteal osteosaroma is usually more mature in the center than at the periphery. WSI digital slide: https://kikoxp.com/posts/4606. Causes: corticosteroid use, sickle cell disease, trauma, Gaucher's disease, renal transplantation. The epiphysis, metaphysis and diaphysis may be involved. Here Melorrheostosis of the ulna with the appearance of candle wax. Amsterdam: Elsevier; 1993. 2021;13(22):5711. 1989. Imaging of skull vault tumors in adults: Author: Pons Escoda, Albert Naval Baudin, Pablo . At the periphery of the infarct a zone of relative high signal intensity on T2WI may be found. A periosteal reaction is a non-specific reaction and will occur whenever the periosteum is irritated by a malignant tumor, benign tumor, infection or trauma. Contact Information and Hours. Wide zone of transition 5, In the cases with no known primary malignancy that are being followed with serial imaging, if the lesion increases in diameter by greater than 25% at 6 months or less, or greater than 50% at 12 months, open biopsy has been recommended by Brien et al. Bone cyst is one of the manifestations of CGL with AGPAT2 mutation. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. Multiple enchondromas and hemangiomas are seen in Maffucci's syndrome. Notice that the cortical bone extends into the lesion. 2014;71(1):39. The differential diagnosis mostly depends on the review of the conventional radiographs and the age of the patient. Notice the numerous ill-defined osteoblastic metastases. In this chapter, we will discuss key imaging features that strongly indicate the lesion is benign and those that warn further evaluation is warranted. This part corresponds to a zone of high SI on T2-WI with FS on the right. About Us; Staff; Camps; Scuba. Common: Metastases, multiple myeloma, multiple enchondromas. diffuse sclerotic metastases to the pelvis, sacrum and femurs. For those that are possibly cancerous, a biopsy is conducted to identify it. 5. A mnemonicfor remembering the causes of diffuse bony sclerosis is: ADVERTISEMENT: Supporters see fewer/no ads, Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. These tumors may be accompanied by a large soft tissue mass while there is almost no visible bone destruction. 2017;11(1):321. Osteoblastic metastases have a lower fracture risk than lytic or mixed bone metastases 11-13. post-treatment appearance of any lytic bone metastasis. Here a lesion in the epiphysis, which was the result of post-traumatic osteonecrosis. Imaging: There are two tumor-like lesions which may mimic a malignancy and have to be included in the differential diagnosis. {"url":"/signup-modal-props.json?lang=us"}, Yap K, Knipe H, Niknejad M, et al. Here two patients with a bizar parosteal osteochondromatous proliferation (BPOP), also called Nora's lesion. Usually typical malignant features including permeative-motheaten pattern of destruction, irregular cortical destruction and aggressive (interrupted) periosteal reaction. However, these lesions are often underreported, mainly because the subject is not well known to general radiologists who struggle with the imaging approach and disease entities. Macedo F, Ladeira K, Pinho F et al. Sclerosis is present from either tumor new bone formation or reactive sclerosis. The images show on the left a typical osteolytic NOF with a sharp sclerotic border. Frequently encountered as a coincidental finding and can be found in any bone. On the left three bone lesions with a narrow zone of transition. The lesson here is that when we are dealing with a very common disorder, even its less common presentations will be seen commonly. Intense uptake on bone scintigraphy as we would expect in high grade chondrosarcoma. The image on the right is of a different patient who has an old NOF that shows complete fill in. The role of imaging in SN lymphomas is to identify the primary site of disease, site for biopsy and to map the lesion in its entirety in cases of patients undergoing radiotherapy [ 15, 21 ]. Polyostotic lesions (2007) ISBN:0781765188. AJR Am J Roentgenol. In the subchondral bone, the number of TRAP-positive cells peaked on day 14. There are no calcifications. An aggressive type is seen in malignant tumors, but also in benign lesions with aggressive behavior, such as infections and eosinophilic granuloma. These lesions were possibly misinterpreted as new when applying WHO criteria. CT-HU has stronger correlations with DEXA than MRI measurements. 4. Differentiation of Predominantly Osteoblastic and Osteolytic Spine Metastases by Using Susceptibility-Weighted MRI. A brain MRI can . A periosteal chondroma may have the same imaging characteristics, however, these are almost always much smaller. Differentiating a bone infarct from an enchondroma or low-grade chondrosarcoma on plain films can be difficult or even impossible. Non-ossifying fibroma which has been filled in. The contour of the involved bone is usually normal or with mild expansive remodelling. Benign periosteal reaction Polyostotic lesions > 30 years Halo of increased signal on T2 W images about the low signal central lesion is suggestive of metastatic disease. Osteopetrosis and pyknodysostosis are likewise hard to mistake for other entities since the bones are denser than in any other disorder, and the long bones tend to have very tiny medullary canals. Usually one bone is involved. Bone metastases are the most common malignancy of bone of which sclerotic bone metastases are less common than lytic bone metastases. Here a patient with a mineralized mass in the soft tissues. Paget disease is a chronic disorder of unknown origin with increased breakdown of bone and formation of disorganized new bone. Moreover, questions such as the . A periosteal reaction with or without layering may be present. Materials and Methods D'Oronzo S, Coleman R, Brown J, Silvestris F. Metastatic Bone Disease: Pathogenesis and Therapeutic Options. Diffuse bony sclerosis (mnemonic) Last revised by Joshua Yap on 28 Jun 2022 Edit article Citation, DOI & article data A mnemonic for remembering the causes of diffuse bony sclerosis is: 3 M's PROOF Mnemonic 3 M's PROOF M: malignancy metastases ( osteoblastic metastases) lymphoma leukemia M: myelofibrosis M: mastocytosis S: sickle cell disease A cold bone scan is helpful in distinguishing the bone island from a sclerotic metastasis, whereas a warm bone scan is nondiagnostic. Publicationdate 2010-04-10 / update 2022-03-17. SWI:low signal intensity on the inverted magnitude and phase images 9. Osteosarcoma (2) This is opposed to myositis ossificans which may present very close to the cortical bone, but maturation develops from the center to the periphery. Centrally there is an ill-defined osteolytic area. . Amsterdam: Elsevier, 1993. BallooningBallooning is a special type of cortical destruction.In ballooning the destruction of endosteal cortical bone and the addition of new bone on the outside occur at the same rate, resulting in expansion. Sclerosing bone dysplasias are skeletal abnormalities of varying severity with a wide range of radiologic, clinical, and genetic features. If the disorder it is reacting to is rapidly progressive, there may only be time for retreat (defense). When considering Pagets disease, it is extremely helpful to note whether there is associated bony enlargement. Radiologe. Finally, we conclude with a case of an incidentally presenting sclerotic vertebral body lesion. brae in keeping with diffuse bone infarcts. 10. Here a chondrosarcoma of the left iliac bone. Radiographs are specific but suffer from low sensitivity 1. Secondary bone cancer is much more common than primary bone . Infections, a common tumor mimicker, are seen in any age group. Wayne State University, Orthopaedic Surgery, MI, 2007 University of Texas Southwestern Medical School, Surgery, TX, 2002 The pathogenesis of myeloma-related bone disease (MBD) is the imbalance of the bone-remodeling process, which results from osteoclast activation, osteoblast suppression, and the immunosuppressed bone marrow microenvironment. On the right T2-WI with FS of same patient.. growth of osteohondroma in skeletally mature patients, irregular or indistinct surface of lesions, soft tissue mass with scattered or irregular calcifications. Osteoblastic Metastatic Lesions. 7. More heterogenous and irregular with bony trabecular destruction and possible extension beyond the confines of the cortex. Sclerotic bone metastasis as initial manifestation of lung adenocarcinoma in a patient with SLE - The Lancet Oncology Clinical Picture | Volume 24, ISSUE 3, e144, March 2023 Sclerotic bone metastasis as initial manifestation of lung adenocarcinoma in a patient with SLE Prof Ruchi Mittal, MD Debashis Maikap, MD Pallavi Mishra, MD found incidentally on the imaging studies. CT can detect osteoblastic metastases with a higher sensitivity than plain radiographs and shines in the assessment of bones which are characterized by a small bone marrow cavity and a high amount of cortical bone such as the ribs 2,3. Patients with sclerotic lesions due to metastasis often have a history of prior malignant disease. Enchondroma is a fairly common benign cartilaginaous lesion which may present as an entirely lytic lesion without any calcification, as a dense calcified lesion or as a mixed leson with osteolysis and calcifications. Symptoms are usually absent, however, in adult patients with a chondroid lesion in a long bone, particularly of larger size, always consider low-grade chondrosarcoma. Infections and eosinophilic granulomaInfections and eosinophilic granuloma are exceptional because they are benign lesions which can mimick a malignant bone tumor due to their aggressive biologic behavior. Radiographs are specific but suffer from low sensitivity 1. some benign entities in this region may mimic malignancy if analyzed using classical bone-tumor criteria, and proper patient management requires being familiar with these presentations. Semin. Sclerotic Lesions of the Spine 1311. predominant hypointensity on all imaging sequences mimicking a sclerotic process due to a variety of fac- . I think that the best way is to start with a good differential diagnosis for sclerotic bones. . Sclerotic or blastic bone metastases can arise from a number of different primary malignancies including prostate carcinoma (most common), breast carcinoma (may be mixed), transitional cell carcinoma (TCC), carcinoid, medulloblastoma, neuroblastoma, mucinous adenocarcinoma of the gastrointestinal tract (e.g., colon carcinoma, gastric carcinoma), These lesions are not osteochondromas, but consist of reactive cartilage metaplasia. Here are links to other articles about bone tumors: Most bone tumors are osteolytic. Solitary sclerotic bone (osteosclerotic or osteoblastic) lesions are lesions of bone characterized by a higher density or attenuation on radiographs or computer tomography compared to the adjacent trabecular bone. The location of a bone lesion within the skeleton can be a clue in the differential diagnosis. There are two patterns of periosteal reaction: a benign and an aggressive type. Ahuja S & Ernst H. Osteoblastic Bone Metastases in Medullary Thyroid Carcinoma. Uncommonly it can be difficult to differentiate a stress fracture from a bone tumor like an osteoid osteoma or from a pathologic fracture, that occurs at the site of a bone tumor. This solitary, uniformly high-density lesion with neither edema in the surrounding bone marrow nor extension into the surrounding soft tissue most likely represents a giant bone island. Small area of lucency with adjacent sclerosis at the distal right medial femoral metaphysis that could relate to enthesopathic change or remodeling of a fibroxanthoma of bone.. Localisation: femur, tibia, hands and feet, spine (arch). Lesions in the bone are usually identified on radiographic images - chiefly X-rays - but also on CT and MRI scans. 2015;7(8):202-11. Regarding bone disease in SM, increased sBT levels have been 493 associated with both bone sclerosis (due to unknown mechanisms) (8, 18, 19) and 494 osteoporosis (it has been hypothesized that tryptase could induce the production of 495 OPG (61)) (4, 17). Case 7: metastases from prostate carcinoma, Sclerotic bone pseudolesions - external artifact, bizarre parosteal osteochondromatous proliferation (Nora lesion), conventional intramedullary chondrosarcoma, dysplasia epiphysealis hemimelica (Trevor disease), solitary bone plasmacytoma with minimal bone marrow involvement, mixed lytic and sclerotic bone metastases, Lodwick classification of lytic bone lesions, Modified Lodwick-Madewell classification of lytic bone lesions. Age is the most important clinical clue in differentiating possible bone tumors.There are many ways of splitting age groups, as can be seen in the table, where the morphology of a bone lesion is combined with the age of the patient. Radionuclide bone scan shows a classic "double density" sign of osteoid osteoma located in the tibia: markedly increased radioactivity in the center ( arrow) is related to the nidus, less active areas ( arrowheads) represent reactive sclerosis. In some locations, such as in the humerus or around the knee, almost all bone tumors may be found. They can affect any bone and be either benign (harmless) or malignant (cancerous). A Codman's triangle refers to an elevation of the periosteum away from the cortex, forming an angle where the elevated periosteum and bone come together. There is a metastasis, which presents as a subtle sclerotic lesion in the humerus metaphysis. Surrounded by a prominent zone of reactive sclerosis due to a periosteal and endosteal reaction, which may obscure the central nidus. 6. Henry Ford Hospital, Neuro Surgery, MI, 1999 Universitat Dusseldorf, Neuro Surgery, 1990 Universitaire Instelling Antwerpen, Neuro Surgery, 1983 When considering hyperparathyroidism, look for evidence of subperiosteal bone resorption. Clin Orthop Relat Res. Fibrous dysplasia, Enchondroma, NOF and SBC are common bone lesions.They will not present with a periosteal reaction unless there is a fracture.If no fracture is present, these bone tumors can be excluded. Click here for more examples of eosinophilic granuloma. Sclerotic jaw lesions are not rare and are frequently encountered on radiographs and computed tomography (CT). AJR Am J Roentgenol. There is reactive sclerosis with a nidus that is barely visible on the radiograph (blue arrow), but clearly visible on the CT (red arrows). Hall F & Gore S. Osteosclerotic Myeloma Variants. There are a number of other helpful findings you can look for that can help you to cone in on or away from specific entities in one of these differential lists. However, cancers that metastasize to bone are very common. Chrondroid tumors are more frequently encountered than bone infarcts. Adam Greenspan, Gernot Jundt, Wolfgang Remagen. ADVERTISEMENT: Supporters see fewer/no ads. Mass displaces and involves both the right 10 th intercostal artery, as well as more superior right 9 th intercostal artery. 2010;35(22):E1221-9. Causes include trauma, infection, autoimmune diseases, inflammatory diseases, spinal degeneration, congenital malformations, and benign or cancerous tumors. Osteoma consists of densely compact bone. Less common: Fibrous dysplasia, Brown tumors of hyperparathyroidism, bone infarcts. FD is often purely lytic, but may have a groundglass appearance as the matrix calcifies. This occurs in early knee osteoarthritis and indicates the potential for cartilage loss and misalignment of a knee compartment. Mixed lytic and sclerotic bone metastases are characterized by the presence of both components, that is areas of bone destruction and areas of increased bone formation within one metastatic tumor deposit or one primary tumor that features both kinds of bone metastases, namely osteolytic and osteoblastic metastases 1. DD: juxtacortical chondrosarcoma, parosteal osteosarcoma. In most cases of osteoid osteoma the radiographic appearance is determined by the reactive sclerosis. Mnemonic for multiple oseolytic lesions: FEEMHI: Not infrequently encountered as coincidental finding at later age. Another finding classic for Pagets disease is that it almost always starts at one end of a bone and then spreads toward the other end of the bone. Sclerotic bone lesions as a potential imaging biomarker for the diagnosis of tuberous sclerosis complex Authors Susanne Brakemeier 1 , Lars Vogt 2 , Lisa C Adams 2 , Bianca Zukunft 3 , Gerd Diederichs 2 , Bernd Hamm 2 , Klemens Budde 3 , Kai-Uwe Eckardt 3 , Marcus R Makowski 2 4 Affiliations Here a 44-year old male with a mixed lytic and sclerotic mass arising from the fifth metacarpal bone. The illustration on the left shows the preferred locations of the most common bone tumors. 4 , 5 , 6. Age: most commonly seen in 10-25 years, but may occur in older patients. Some prefer to divide patients into two age groups: 30 years. The bone marrow compartment is not involved which is important for the surgical strategy. You can then customize the above differential for whichever pattern of sclerosis that you see. The most reliable indicator in determining whether these lesions are benign or malignant is the zone of transition between the lesion and the adjacent normal bone (1). Ulano A, Bredella M, Burke P et al. Plain radiograph in another patient shows irreglar mineralized lesion with elevation of the periosteum and cortical involvement. Notice how easily MRI depicts these lesions. 2 ed. Chordoma is usually seen in the spine and base of the skull. Large lesions tend to expand into both areas. It is associated with near total fat loss, severe insulin resistance and hypoleptinemia leading to metabolic derangements.Case PresentationWe report a 25- year- old female with 1-Acylglycerol-3-phosphate-O-acyltransferase 2 (APGAT2) mutation, and both sclerotic and lytic bone lesions together for the first time. O'Sullivan G, Carty F, Cronin C. Imaging of Bone Metastasis: An Update. Spinal lesions are commonly spotted on imaging tests. Typical bone metastases are osteolytic (87.5%), with medullary origin (91.6%), and they cannot be distinguished from other osteolytic metastases on the basis of imaging criteria alone. General Considerations The sclerotic lesion in the humeral head could very well be a benign enchondroma based on the imaging findings. Fundamentals of diagnostic radiology. A lumbar puncture (LP) is a diagnostic procedure used to obtain a sample of cerebrospinal fluid (CSF) to look for signs of infection or inflammation. Brant WE, Helms CA. It is true that the usual appearance of skeletal metastases is that of focal lesions diffuse sclerosis occurs in only a small fraction of cases of skeletal metastases. It is barely visible within the bone, but an agressive periostitis is seen (arrow). Here some typical examples of bone tumors in the foot: Fundamentals of Skeletal Radiology, second edition Here CT-images of a patient with prostate cancer. T2-weighted axial MR image demonstrates high signal intensity of the tumor in the metacarpal bone with extension of a lobulated soft tissue mass. It is nost commonly located on the posterior side of the distal meta-diaphysis of the femur. At Henry Ford Orthopaedics in Chelsea our mission is to provide personalized treatment plans specific to each patient, to ensure the best possible outcome.
